"One Blue Bonnet" unveils the remarkable journey of Frank Coutts, an army veteran who dedicated his life to noble causes. After retiring, he fervently championed Scottish regiments and charitable endeavours. His advocacy was ignited by the government's decision to cut infantry regiments during active overseas deployments, spurring his support for the "Save Our Scottish Regiments" campaign. This book encapsulates Coutts' fervour as he rallied for the preservation of historical regiments, including the King's Own Scottish Borderers.

A decorated military career took him across the globe, from wartime service as a platoon commander during fierce battles in Europe to international rugby stardom representing Scotland. From the jungles of Malaya to cold-war Berlin's streets, his journey weaves a captivating narrative. The memoir, first published in 1991 and reissued to mark his 90th birthday, pays homage to one of his generation's most revered soldiers. Coutts' legacy lives on through his charitable work, especially with the Seagull Trust, offering canal cruises to thousands in Scotland annually. His enduring dedication, valour, and advocacy form the heart of "One Blue Bonnet."
